Homebrew PCBs

Uh, change in plans.  I've been fiddling around with the 24V motors I have
on hand and they appear to be VERY demagnetized.  I didn't notice this until
I picked up a set of smaller steppers and noticed a drastic difference in
resistance.

So now I have to get myself decent steppers.  I'm not going back to the
local surplus store, I'll just get the same problem (dozens of steppers all
piled in the same box).  I'm going to buy larger motors for the CNC machine
later, but for now, I'm looking for decent intermediate motors that will
make my drilling station work as well as machine wood and plastics.

I was checking these pulls from Xylotex:

Problem is now I have to reconsider a totally new driver circuit 'cause
these are bipolar steppers.  Can I modify my schematic without TOO much
trouble?  Or am I better using a new design?

Argh, back to square one...
